Spi 29-016-3 Class Zz Plus Plug Gage 0.016 in

Product Description

The SPI 29-016-3 is a Class ZZ Plus plug gage designed for precision hole inspection in machining and manufacturing environments. It measures a nominal bore diameter of 0.016 inches with a tolerance of 0.0002 inches, making it suitable for verifying tight-tolerance drilled, reamed, or punched holes. Constructed from steel for durability and dimensional stability, this gage is a go or no-go inspection tool used by machinists, quality control technicians, and toolroom professionals who need reliable, repeatable measurements at the bench or on the shop floor.

This plug gage is used in precision manufacturing settings where small-diameter hole conformance must be verified against print specifications. Typical applications include inspection of holes in metal components, die work, medical device manufacturing, and any production environment requiring verification of 0.016-inch diameter bores. It is appropriate for both incoming inspection and in-process quality checks.

Key Features

• Class ZZ Plus tolerance classification for reliable go or no-go inspection at 0.016 inches nominal diameter
• Tolerance of 0.0002 inches supports tight-tolerance bore verification
• Steel construction provides dimensional stability and resistance to wear
• Compact, single-unit design suited for bench inspection or in-process use
• Lightweight at 0.2 pounds for easy handling during repeated inspection cycles

Compatibility

Designed as an OEM-style precision inspection tool for verifying 0.016-inch diameter bores in machined or fabricated components where Class ZZ Plus gage standards apply.

Installation Notes

Plug gages are handled and used by machinists or quality technicians and require no permanent installation. Clean the gage and the bore being inspected before use to prevent debris from affecting readings. Store in a protective case away from moisture and temperature extremes to maintain calibration integrity. Periodic recalibration against a traceable standard is recommended per your quality management system requirements.
